CNCMTB Hydraulic Disc Brake Set，Bike Disc Brake Sets Front and Rear Line Pulling Hydraulic Disc Brake，Red/Purple. …

It fitted my mountain bike front wheel perfectly and significantly improved breaking. Real benefit is it is clamping the disc from both sides instead of pushing from only one side. Gets rid of vibration when breaking and stops really fast if you put pressure on.

This product pretty quickly lost breaking power. Pads have been adjusted, but I guess it lost hydraulics. Also, where the cable attaches it continually works the cable and eventually frays and breaks it

works well, easy to install

The brake is good, when adjusting it beware the the pistons don’t move at the same time, first the left, then the right, also the brake pads were slightly contaminated which doesn’t brake very good, just have to sand and clean it

Front and back starts squealing after a week of easy riding. Very disappointed.

Well let me think, EVERYTHING ABOUT THESE CALIPERS IS COMPLETELY CRAP.

The brakes installed with no effort but I’m an experienced mechanic. Instructions would be helpful or links for that. The performance is extremely good & well worth the $$

Just got them now to see if they work tho they same as before and lasted a year before started leaking oil

Quality control for this product is non-existent. Wasted 50$ on this caliper as it lasted only a week. You get what you pay for...

Bought this hoping to solve the poor braking performance of the mechanical front caliper that came with my bike. I had it installed and adjusted in minutes. This works so much better, even using the original rotor. The pads are also a little larger and oblong compared to the smaller, round pads of the original. Great purchase.

easy to install. they don,t stop any better but no squealing and even brake wear. much heavier than the old calipers.

Good: Look cool, and the braking is excellent!Con: The hand lever need way more force to activate this semi-hydraulic brake.
